Specifiers and fabricators requiring the unique combination of high corrosion resistance and outstanding material strength provided by duplex stainless steels now have freely available to them a definitive guide to selecting and working with duplex grades.

A major update of ‘Practical Guidelines for the fabrication of Duplex Stainless Steels’ brings together in one publication experience from around the world. It goes beyond the first and second generations of these materials also taking into account the latest developments in lean duplex and hyper duplex grades.

This publication is available in English and Chinese (clicking on the language will open the pdf).

This module contains 61 pages and 18 interactive functions (8 animated illustrations) designed to introduce you to the practices that will allow you to transport, store, cut, form, weld and clean austenitic stainless steels in such a way as to preserve their corrosion resistance and aesthetic qualities.

Contains 31 tables and 40 figures on the metallurgical characteristics of stainless steels and the changes that can take place during welding. Aspects covered include different welding and joining methods, joint designs and weld filler-metal selection. Also discusses pipe welding, weld overlays, welding clad plate, welding dissimilar metals, and post-weld cleaning and finishing.

Stainless steels have optimum resistance to corrosion when clean and free of scale. This AISI publication describes several pickling and cleaning methods. Acids and typical cleaning systems are identified, variations in time, temperature, and techniques are discussed.

This document provides information about stainless steel fabrication practices and their implications on corrosion behaviour when exposed to waters and waste waters. This information is intended for fabricators, designers, specifiers and end users. Originally written to assist engineers involved in the United Kingdom's water industry, its content is also relevant internationally. Additional information, frequently requested, about grade selection guidelines, alloy properties, design and health and safety aspects are also included.

English edition. Based on the Technical Manual for the Design and Construction of Roofs of Stainless Steel Sheet, published by JSSA in 1985. It comments on processes in use in Japan for welding stainless steel, and includes a practical commentary on structural methods and construction, taking into account the climate and construction technology of Japan.

This Nickel Institute publication is presented in three sections: "For the welder," deals with the differences in welding techniques for nickel-containing stainless steels, versus conventional carbon steels; "For the materials engineer," describes various types of stainless steels and how their metallurgical and corrosion resistant characteristics are affected by welding and heat treating; and, "For the design engineer," which demonstrates how the corrosion performance of stainless steels can be enhanced by good design.

Chromium may occur in several valence states: chromium in metallic form (valence state 0), trivalent form (Cr III), and hexavalent form (Cr VI) are the most common and important. Trivalent chromium (Cr III) occurs widely in nature and is an essential nutrient required by the human body to promote the action of insulin in body tissues. Chromium as a pure metal has no reported human or environmental toxicity effects. Both acute and chronic toxicity of chromium are mainly caused by hexavalent chromium compounds (Cr VI).

This document provides information about stainless steel fabrication practices and their implications on corrosion behaviour when exposed to waters and waste waters. Aspects of grade selection guidelines, alloy properties, design and health and safety aspects are also included.

For many years, stainless steel low pressure fittings have been manufactured to dimensions of cast (ANSI B16.3) malleable iron and wrought steel (BS 1740) fittings standards. These standards have governed the majority of readily available stainless steel products in Australia.

Forming methods are discussed and include cutting, sawing, shearing, plasma cutting, blanking, punching, piercing, bending, drawing, spinning and tube bending.

An overview of welding stainless steels is given, with particular reference to the various welding methods that can be used. Standards mentioned include BSEN1600 BSEN12072 BSEN12073 BSEN760 BSEN287 Part1 (Approved testing of welders for fusion welding) BSEN288 Part 3 Welding Procedure tests for the arc welding of steels.

The importance of good design and surface finish selection for the successful fabrication of stainless steel is outlined along with some of the properties that can affect the fabrication and performance of stainless steels.

Welding inevitably produces contamination of the steel surface, not least of which is the heat tint at the weld line. Care must be taken to minimise and control this contamination. Similarly care must be taken when designing and implementing stud welded structures. Welded structures should normally be cleaned after fabrication. Various methods are available which may influence the aesthetics of the unit. This can be advantageous.

Stainless steels are selected for applications where their inherent corrosion resistance, strength and aesthetic appeal are required. However, dependent on the service conditions, stainless steels will stain and discolour due to surface deposits and so cannot be assumed to be completely maintenance-free. In order to achieve maximum corrosion resistance and aesthetic appeal, the surface of the stainless steel must be kept clean. Provided the grade of stainless steel and the surface finish are correctly selected, and cleaning schedules carried out on a regular basis, good performance and long service life will result.

Practical advice on how to avoid weld imperfections when welding different types of stainless steel.

Aspects of laser welding heavy-section duplex are discussed.

Techniques for underwater welding of stainless steels are explored.

The pros and cons of welding with both types of filler electrodes are discussed.

A high nitrogen alloyed iron base filler metal has been developed aiming to overcome some of the difficulties associated with nickel-based fillers.

When welding superaustenitic stainless steels, the common practice is to use nickel base fillers overalloyed with molybdenum. This paper discusses metallurgical aspects.

Stainless steel is a family of more than one hundred metallic alloys. Their common feature is that they have a maximum carbon content of 1.2% and a minimum chromium content of 10.5%.  Within this family of grades, there are different degrees of corrosion resistance to various media – from the very mild conditions in the interior of office buildings to the more corrosive conditions prevailing in an external marine environment or the splash zones of building components exposed to de-icing salt or sea water.

In nine case studies, this publication describes how stainless steel makes it possible to fabricate exceptionally complex shapes involving as few parts and welds as possible. Minimizing the number of forming operations or heat treatments, the stainless steel solution can also be particularly cost-effective.

Descaling, removing mild discoloration, and the definition of passivation are discussed. Comments on handling, care in the shop, and cleaning procedures.

The corrosion resistance of stainless steel is due to a 'passive', chromium-rich complex, oxide film that forms naturally on the surface of the steel. This is the normal condition for stainless steel surfaces and is known as the 'passive state' or 'passive condition'.

Architects specify stainless steel for its excellent corrosion resistance as well as for its visual qualities. Good fabrication is essential to maintain both these features. Stainless steel is not more difficult to cut, form and join than other metallic materials, but it may be different. Respecting those small differences is the key to success.
